SCI Chester is a Pennsylvania state correctional institution operated by the Pennsylvania Department of Corrections (DOC). The DOC describes it as a medium-security institution for men. It sits at 500 East 4th Street in the City of Chester, Delaware County, near the Delaware River.
According to the DOC, SCI Chester was the 24th state correctional institution to open in Pennsylvania, and its original mission paired public safety with substance use treatment. Today the DOC lists academic education, vocational training, substance use treatment and reentry programming among the institution's offerings, along with its housing units, including the Little Scandinavia Housing Unit.
People at SCI Chester are held under the state's correctional authority, generally after a court has imposed a state sentence. That makes SCI Chester very different from a county jail: it does not book new arrests, and it does not run a county bail posting window. County detention and bail functions in Delaware County are handled through the courts and George W. Hill Correctional Facility in Thornton.
